ABSTRACT:
A distributed session failover mechanism is disclosed for facilitating the replication and retrieval of session information. A first server, in a trusted network, providing a single sign-on (SSO) solution, stores session information pertaining to a particular client requesting services associated with the server. In order to provide session failover, the first server sends a copy of the session information to a bus mechanism, which is connected to one or more persistent repositories. When a second server attempts to validate the client, the second server may discover that the first server failed. The second server then requests a copy of the session information pertaining to the client from the bus mechanism. The bus mechanism retrieves the copy from a persistent repository and provides the copy to the second server.
